TeraFractal lets you create and display fractal images that are based on an iterated function system. But rather than forcing you to define transformations numerically, TeraFractal represents each transformation as a rectangle in a control window. You make adjustments by simply manipulating these rectangles with the mouse to alter the translation, rotation, and scaling factors. This representation also allows you to see the properties of a given iterated function system at a glance. (See screen shot.)
TeraFractal updates the fractal image continually by using an efficient randomized algorithm that iteratively applies the transformations to a random starting point. This real-time feedback makes it possible to create lifelike fractals in a surprisingly short time.
